INTRODUCTION
The ART Pro Channel II™ is the answer to your recording and computer audio interface needs. Our second-
generation discrete Class-A microphone preamp provides clean quiet gain while maintaining incredible
transparency. A powerful dynamics processor subtly controls transients and noise of the most demanding
sources. The ART Pro Channel II™ ’s semi-parametric EQ offers wide tune-ability and can be patched before
OR after the dynamics processor. Separate insertion jacks allow you to use your favorite external signal
processing gear immediately after the Mic preamp and before the EQ and dynamics processor. Both analog
and LED meters provide a detailed indication of audio levels.
INSTALLATION
The ART Pro Channel II™ may be used in a wide variety of applications and environments. In a rack-
mountable, all-steel enclosure, the unit is designed for continuous professional use. Mounting location is not
critical, however for greater performance reliability we recommend that you not place the unit on top of power
amps, or other sources of heat and/or strong magnetic fields. The tube circuitry needs about a minute to “warm
up” and stabilize from a cold power up.
AC Power Hookup
The ART Pro Channel II™ has an internal power supply. Only connect the unit to mains power of the type
marked on the rear panel. The power source must provide a good ground connection, and the ground pin on
the mains plug should never be defeated.
